ButtonNode

Namespace: Hex1b

Assembly: Hex1b.dll

public sealed class ButtonNode : Hex1bNode

Inheritance

Object → Hex1bNode → ButtonNode

Properties

ClickAction

The async action to execute when the button is activated. This is the wrapped handler that receives InputBindingActionContext.

Returns: Func<InputBindingActionContext, Task>

public Func<InputBindingActionContext, Task>? ClickAction { get; set; }

HitTestBounds

Hit test bounds are limited to the actual button content, not the full arranged bounds. If the button hasn't been arranged (Bounds is zero), returns empty bounds to prevent accidental hits on nodes that are scrolled out of view or otherwise not displayed.

Returns: Rect

public override Rect HitTestBounds { get; }

IsFocusable

Returns true if this node can receive focus.

Returns: Boolean

public override bool IsFocusable { get; }

IsFocused

Gets or sets whether this node is currently focused. Only meaningful for focusable nodes (where IsFocusable is true).

Returns: Boolean

public override bool IsFocused { get; set; }

IsHovered

Gets or sets whether the mouse is currently hovering over this node. Set by Hex1bApp based on mouse position during each frame. Only set on focusable nodes (tracked via FocusRing hit testing).

Returns: Boolean

public override bool IsHovered { get; set; }

Label

Returns: String

public string Label { get; set; }

SourceWidget

The source widget that was reconciled into this node. Used to create typed event args.

Returns: ButtonWidget

public ButtonWidget? SourceWidget { get; set; }

Methods

ConfigureDefaultBindings(InputBindingsBuilder)

Configures the default input bindings for this node type. Override in derived classes to add default key bindings. These bindings can be inspected and modified by the user's callback.

Parameters:

• bindings (InputBindingsBuilder): The builder to add bindings to.

public override void ConfigureDefaultBindings(InputBindingsBuilder bindings)

MeasureCore(Constraints)

Override this method to implement measuring logic for this node.

Parameters:

• constraints (Constraints):

Returns: Size

protected override Size MeasureCore(Constraints constraints)

Render(Hex1bRenderContext)

Renders the node to the given context.

Parameters:

• context (Hex1bRenderContext):

public override void Render(Hex1bRenderContext context)
